-------------------------------

             Summary: refine excludeParams of ParametersInterceptor to improve security 
                 Key: WW-4332
                 URL: https://issues.apache.org/jira/browse/WW-4332
             Project: Struts 2
          Issue Type: Improvement
          Components: Core Interceptors
            Reporter: zhouyanming
            Priority: Critical


{code}
(.*\.|^)class\..*
{code}
should be 
{code}
(.*\.|^)class(\.|\[).*,.*\['class'\](\.|\[).*,.*\["class"\](\.|\[).*
{code}

it will block such as
{code}class['classLoader']  , model['class'].classLoader , model["class"].classLoader {code}

I think use regex to block parameterName is not best solution,It must be done in ValueStack, seperate entry point , one for serverside, one for client side,client side should add more restriction and security checks.
